- FINGER-RING.

SPECIFICATION forming part of Letters Patent No. 768,282,;1ated August 23, 1904.

Application filed June 15, 1904.

To all whom it may concern.- I

Be it known that I, GEORGE W. HU'IOHISON,

' a citizen of the United States, residing at Providence, in the county of. Providence and State of Rhode Island, have invented a new and .use-

ful Improvement in Finger-Rings, of which the following is a specification.

Th1s invention has reference to an improvement in finger-rings, and more particularly to an improvement in the means for detachably securing a signet-plate flush with the head of a signet finger-ring.

The object of my invention is to detacha'bly .secure a Signet-plate in the box-head of a finger-ring flush with the head of thering by,

turning'a screw-head on the under side of the ring-head.

A further object of my invention is to raise the Signet-plate above the head of the ring by a reverse movement of the screw-head, thus making the signet-plate more accessible for removal from the ring than has heretofore been done.

My invention consists in the peculiar and novel construction of a signet finger-ring, said ring having a hollow box-head of any shape desired, a Signet-plate adapted to fit flush in the boX-head-having on its face a letter of the alphabet and on its under side a collar centrally located, in which are two oppositelydisposed pins extending inwardly, and a screwheaded cam-cylinder centrally and rotatably secured to the bottom of the box-head with the screw-head on the under side of the boxshowing the detachable signet-plate, in the face of which is cut or stamped a letter of the alphabet. Fig. 3 isan enlarged face view of Serial No. 212,694. (Nd model.)

the ring with the Signet-plate removed. Fig. 5 4 is an underneath view of the Signet-plate removed from the ring. Fig. 5 is a detail transverse sectional view through the ringhead and Signet-plate. showing the signetplate flush with the ring-head in full lines and in its raised position in broken lines; and Fig. 6 is a detail sectional view through the ring head and cam-cylinder, showing the means for rotatably securing the cam-cylinder to the ring-head.

In the drawings, a indicates the ring, I) the cam-cylinder, and '0 the detachable signetplate. The ring a has the oval hollow boX head a, in the bottom of which is the centrally-located outside beveled hole a The 5 cam-cylinder I) has the spiral cam-groove b in its periphery, connecting with ,the oppo-' sitely-disposed openings 6 b? in the top and the central hole 6 as shown in Fig. 6. A stud 6, having the screw-head Z2 and the shoul- 7o der'b is pushed upward through the beveled hole a in the ring-head a and through the central hole 6 in the cam-cylinder, and the cam cylinder firmly secured to the stud by upsetting the upper end of the stud on the end of the cam-cylinder, as shown in Fig. 6. The screw-head 6 can now be turned in the beveled hole 65 and with it the cam-cylinder b.

The detachable Signet-plate c is shaped to fit in the box-head a flush with theface'of o the head. In the face of the signet-plate c'is cut or stamped a letter of the alphabet 0 or other sign, as shown in Fig. 2. Gentrallylocated on the under side of the Signet-plate, in a position to fit over the cam-cylinder b, is the 5 collar 0 having the inWardly-extendingoppositely-disposed pins 0 0 adapted to enter the oppositely-disposed openings 6 b in the top of the cam-cylinder and engage with the spiral cam-groove b in cylinder.

By the use of-my improved Signet-ring a dealer in the trade may carry a small number .of rings and a large assortment of signetplates. I different letter is usually wanted. The camcylinder b is now turned one complete revolution to the left by the screw-head 6 This the periphery of the 90.

After fitting the buyer as to size a raises the Signet-plate 0 into the position as shown in broken lines in Fig. 5, bringing the pins 0 a" in the collar of the Signet-plate into the openings in the top of the cam-cylinder. The signet-plate can now be easily and quickly removed and a Signet-plate having the required letter secured in its place by placing the collar 0 of the Signet-plate over the camcylinder 6 in a position for the pins 0 c to enter the openings 6 5 in the top of the camcylinder, which is now turned one complete revolution to the right. The pins 0 c following the cam-groove b, draw the signetplate down flush with the face of the ringhead, firmly securing the-signet-plate in the box-head of the ring. The lower edge of the collar 0 and the bottom of the box-head a form a stop, which limits the inward movement of the Signet-plate.

In the operation of my improved signetring the flush signet-plate is more firmly secured to the ring and more quickly and easily detached from the ring than has heretofore been done.

Having thus described my invention, I claim as new anddesire to secure by Letters Patent 1. A Signet-ring having a hollow box-shaped head and a detachable signet-plate, means for mechanically drawing the Signet-plate down in flush with the ring-head and for raising the Signet-plate above the ring head, consisting of a cam-cylinder rotatably secured to the bottom of the ring-head by a beveled screw-howl. which extends through the ring and revolves the cam-cylinder, a spiral cam-groove in the periphery of the cam-cylinder. a letter or other sign on the face of the signet-platc, a collar on the under side of the signet-plale, andinwardly-extending pins in the collar adapted to engage with the spiral ean1-groove in the cam-cylinder, as described.

2. In a signet finger-ring. the combination of the ring (0 having the hollow box-shaped head a in the bottom of which is the outside beveled hole (1?, the cam-cylinder having the spiral cam-groove Z), the openings 7) If. and the central hole I), the stud I) having the screw-head 7f and the shoulder If secured by pushing the stud upward through the beveled hole a and the central hole I) and upsetting the end of the stud on the end of the cameylinder, and the signet-plate 0 having a letter or other sign out, stamped, or raised on its face and the collar 0 on its underside in which are the pins 0" a, as described.

In testimony whereof] have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE \V. HUTCIIISON.
